Aaaargh. How is this so difficult?! 
Middle name will end in an “a” so trying to avoid that in the first name too.
I prefer older style names -
Madeline, Emmeline, Esme, Persephone, Seraphine (there’s definitely a leaning towards “eeeen” sounding names! etc but DH whilst not hating them hasn’t found one he loves yet.
Surname is quite unusual so would prefer first hand be pronounceable / easy to understand.
Nothing too modern, or won’t pass the “could she be prime minister one day with that name” test
